CVE-2026-107216

high

Description

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.8.1 to 2.11.0, ANCHORARRAY recursively calls the exported CalcCellValue function, creating a fresh calculation context at each cycle and bypassing in-flight and iteration controls. ANCHORARRAY calls CalcCellValue instead of cellResolver, so each recursive hop receives a new calcContext and loses cycle state. When mutually referencing dynamic-array formulas are evaluated directly or through formula-evaluating APIs, each recursion hop resets the cycle budget and prevents completion-based caches from breaking the cycle, allowing an attacker to cause a fatal Go stack overflow and abort the process. No fixed version is available as of this review.
